METALLIC ROOFING, SIDING, AND CEILING.

SPECIFICATION forming part of Letters Patent No. 339,744, dated April 13,1886.

Application filed December 1-2, uses.

To all 10700711 it 72mg concern:

Be it known that I, WiLLLlM H. CUSACK, acitizen of the United States, residingat New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Metallic Roofing, Siding, and Ceilings, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to metallic roofing, siding, and ceilings; and it consists in the construction of the san1e,which will be more fully hereinafter described, and pointed out in the claims.

One object of my invention is to provide metallic roofing and siding which may be attached to the roof or the outside or inside of buildings without exposing to view or to the elements the heads of the nails or screws by which the same is secured, and at the same time shall present a complete covering and protection from rain and storms to the part of the building to which it is attached.

A further object of my invention is to provide metallic roofing or siding which willpen mit of longitudinal or transverse expansion or contraction from the heat of the sun or other cause and still make a complete covering to that part of the building to which it is attached.

A further object of my invention is to provide metallic roofing or siding the several parts of which shall be so corrugated transversel y and diagonally that they will interlock each with the other, and thus prevent any of said parts from being detached or removed from its place, thus preserving a complete covering to such part of the building, outside or inside, to which it may be applied.

A further object of my invention is to provide metallic roofing or siding the parts of which are so constructed and corrugated that they may be placed on aroof or side of abuilding,whether laid from right to left, left to right, from the highest to the lowest point, or the lowest to the highest point, with equal facility and utility.

A further object of my invention is to provide metallic roofing or siding the parts of which are so corrugated as not only to inter- Serial No. 185,515. (Noinodeh) lock each with the other and form a. perfect covering to each part of the building they may he applied to, but at the same time form inner grooves or gutters to carry off any water or moisture which may penetrate or collect on the under or inner side of the same.

I attain these objects by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate similar parts in the several views, and in which- Figure 1 is an elevation of a portion of a roof with my improved metallic sheets ap plied thereto, with a portion of the end of one sheet broken away to illustrate the short oblique corrugations. Fig. 2 is a detail view in perspective of one of the sheets of roofing. Fig. 3 isa detail view in transverse vertical sect-ion of a series of'the sheets of roofing, illustratingl'hc mode of overlapping and securing the same. Fig. 4 is a detail. view in elevation of a roof with a modified form of corrugated roofing -sheet applied thereto. Fig. 5 is a detail view of a modified form of the corrugated metallic sheet.

A indicates a corrugated metallic sheet, which is formed at regular intervals with air gular corrugations u, as illustrated in Fig. 2. The under edges of the metal sheet A are formed with a series of oblique grooves, 110', which may be either concave or convex, and when the edges of two of the sheets overlap the top plain edge of one sheet fits over the corrugated edge of the other. Any water or moisture which may get under the joints is taken up by the corrugations a and directed outwardly onto the corrugations a. As shown in the drawings, these corrugations a" are directed or inclined toward the outer surface of the sheet. The corrugations a are formed with a divisional plane surface, a, and the edges a of each one of the said plane surfaces are bent over, and a portion, a, extends inwardly nearly at right angles to the edge a, extending back from the said edge a at an upward incline. By this means the water or moisture flowing over the edge a will fall on the plane surface a, and so on until it ilows into a common drain. .ly this slightly upward incline a firmer lapping joint is also pro vided, so that when a sheet is secured at one end the corrugations on the free end thereof fit in corresponding corrugations in the other sheet, and are securely held down in consequence of the interlocking of the transverse corrugations.

As seen in Figs. 1 and 4, the sheet A is shown as secured to the rafters or beams directly, dispensing with roofing'boards, the usual mode of construction.

In Fig. 5 a modified form of the sheet is illustrated. In this form the corrugations are so constructed as to form Ushaped divisions, the principle of draining being precisely the same as in the form of sheet heretofore described. This imitation may be varied, and diamond, hexagon, or octagon corrugations may be constructed to represent different styles of roofing tile or slates, which may have suitable painted designs thereon.

As illustrated in Fig. 5, the corrugations in the sheets A are shown in a modified form. In this instance the lower edge, a", of the plane surface a is formed with a suitable surface at right angles to the plane surface a and extends back a short distance. From the point where this angular surface steps a concave corrugation extends inwardly and continues down again into another of the plane surfaces a. This form also provides for a tightly-fitting overlapping joint in a manner similar to the firstdescribed sheet.

In attaching or securing my improved corrugated metallic sheet to the roof, rafters, or joists, one edge, a, is fastened thereto, the other edge being left free and unsecured. Another sheet is then fitted in the corrugations and over the nailed edge of the sheet already set, its end being locked in said corrugations and forming a lap-joint therewith. The end of this last sheet is free and not se cured, but its other end is nailed to its place of securement when the free end of another sheet is interlocked with the fastened edge of the last one. This securing and interlocking of the sheets continues until the structure desired to be covered shall have been finished. By securing one edge only of the metallic sheet the other or free end is allowed a free longitudinal expansion or contraction, moving along the corrugations. A transverse expan* sion or contraction is permitted by the con struction of the corrugations in the form described. This is allowed by the angular indentations of the metallic sheets, which either draw to a right angle on the edges or cause further overlapping of the same. When the sheets are united on their lower sides, they are overlapped in a manner similar to the edges, being secured only at the point where they overlap. When the sheets are joined together, the inside of the entire roof, when completed, is provided with a series of gutters or troughs, which are formed by the indentation of the metal from the outer surface. These inner troughs gather what water or moisture may escape through the overlapping joints or be retained by the inclined corrugations a, which is allowed to flow from one to the other until a common drain is reached. By this construction of overlapping a protection is provided for the nails, they being covered at the free unsecured ends of the interlocked sheets. By the allowance for both longitudinal and transverse expansion or contraction there is no strain exerted upon the nails and a consequent tearing and loosening of the entire roof. These sheets are flexible, and are especially adapted for covering inclined coir caved Mansard roofs or domes or any other concave surface. These sheets are applica ble for sheathing buildings as a substitute for weather-boarding, or for lining the same, and can be made in form to suit any style of architecture.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As an article of manufacture, an interlocking metallic roofing and siding consisting of a corrugated sheet with the corrugations separated by plane surfaces, said corrugated portions extending under and upward at an angle to the said plane surfaces, thereby forming overshoots on the front and drain-troughs in the back portion of said sheets, the sheets being adapted to be secured only on one side, substantially as described.

2. In a roofing and siding, the combination of sheets of flexible material, corrugations separated by plane surfaces formed in said sheets, said corrugations extending under and upward at an angle to the plane faces, and sup plementary corrugations formed obliquely in the one side of each sheet and covered by the interlocking of the next sheet thereon, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
